I have the city vision leds, which look exactly like your picture. I called led92, the company from whom I bought them because I was worried if I needed to place the resistor box outside the light housing due to heat. They said no. When I installed them, I laid the resistor down flat in a little space just next to the light. I have had them in for two weeks now, with no problems at all. I have even pulled one out a few days ago and checked everything, and it all looked fine. BTW, it looks soooo much cooler (and brighter) than stock. Enjoy!
